There are lots of brand new homeschooler starting high school this year.
What worked for you and what did not work? How do you make a push for independence? How do you set up school work accountability? Will you work in dual credits? AP classes (where did will your kids take these tests? Did you get your material approved for AP?), will you do dual enrollment? College classes? Online classes? Any non textbook things you plan to use?
Oh, the list seems endless!
